Forgotten baby syndrome refers to a phenomenon in which young children are mistakenly left in vehicles.
Over 25% of parents with children under 3 have lost awareness of the child being present in the car at any point during the drive.
[16] Diamond has identified common factors of the phenomenon as "stress, sleep deprivation, and change in routine".
[17] There have been several efforts to address the phenomenon through technology, including back-seat alert systems (which note when a backseat is opened prior to driving), car-seat alarms (which detect whether a child is buckled in),[8] and end-of-trip reminders.
[18] The Association of Global Automakers and the Alliance of Automobile Manufacturers have committed to the standardization of rear-seat-occupant alert systems by 2025.
